So i was about to do self love i was breathing heavily its cold here  then after that i suddenly feeling dizziness like I'm bout to faint when i was going upstairs i felt very bad dizziness like I'm bout to fall but nothing happens like that then suddenly i feel like some kind of numbness or squeeze feeling in my heart like i urge to squeeze my heart so badly like when we bath in cold water and our heart feel stiff feeling like that and then i thought I'm having something bad in my heart i sit on the floor call my sister waited for her she came i cried twice she gave me warm water then i go for a walk i was fine after that what was that? Is it really my anxiety?
